Patented June 13, 1933 PATENT OFFICE VICTOR PROSPER GUILLEMIN, OF VIENNE, FRANCE AUTOMATIC GASOLINE VAPOR GENERATOR VJelpplicaition led October 4, '19281, Serial No. 310,368, and iny France October 19, 192i?.

This invention relates to improvements in automatic gasoline vapor generators.

The object of the invention is the automatic continuous production of gas without any personal supervision for periods of months or weeks according to the reserve of petrol in store to give perfect homogeneity of the gaseous mixture and an unvarying composition whatever the rate of discharge.

In existing systems Carburation of air is effected by means of a rotary compressor the movement of which produces a change in the conditions of carburation in proportion to the discharge.

The arrangement according to the present invention is simple without any moving ele` ments and therefore incapable of derangement. Moreover there is no loss of petrol and any loss of mixture by leakage is avoided, hydraulic joints ensuring the conservati`6fof the gas. v

The gas obtained from petrol in large quantities lights immediately from a match y arlid may be utilized in a gas stove or the li e.

The invention will be described with reference to the accompanying diagrammatic drawing.

According to the invention the apparatus comprises a centrifugal fan a driven by an electric motor b to which it is coupled, mounted on one of the walls of the tank.

A regulating bell c' receives combustible mixture under pressure from the fan a after its passage into a Carburettor Q the pressure being imparted by the fan. This bell is in communication with the delivery system through a tube y' which receives carburetted air at a pressure determined by the weight of the bell.

A container 8 contains a quantity of water into which the bell is inserted concentrically with an inner inverted chamber l. This container also supports and protects the mechanism. A receptacle for liquid fuel provided at its center is placed inside the chamber Z.. and comprises a cylindrical gasqlinereservoir m ith/a guide tube n. The wall of said'jrar e is provided with openings 0, 0 which respectively establish fuel and air communication'between the tube and the reservoir, soY that an even pressure is maintained inthe airspace of the reservoir. The reservoir m may be filled by an outside tube p, which in practice is pro-l vided with a valve. I

the chamber t communicating with the portion r through orifices o andwith the interior of the tube n. througha lateral perforated cylindrical side wall having a porous surface ofcloth for example. Ahydraulic check valve y having -two compartments 0 and d is also provided.

-At ythe upper end of the tube n is a; deflector disc w which closes the upper end of said* tube Vand has grooves in its lower slpLV which establish communication betwee he interior of the bell i and the interior of said tube.` AS the carburetted air and the noncarburetted air pass from the tube, they strike the lower side of the disc and are de# flected outwardly thereby and pass vthrough the grooves of the disc and are thereby thoroughly mixed while leaving the tube.

Hence a uniform mixture is at all times suppliedy to the bell.v

A lever a automatically controls the stopping and starting of the motor b which isV driven from a suitable source of electric `power (not shown). y

The operation of the apparatus is as follows If the regulating bell z' is at its lowest position the lever e which rests upon it is low- 5 ered and closes the switch 7c and the fan l pumps air into the two compartments c and d of the hydraulic valve y through pipes c1 and all. The air compartment c is in direct communication with the cylindrical portion 7 of the ioat through a tube e and tube s and with the chamber u ofthe Carburettor through the orifices o from which it can pass through the porous wall a; which dips into the gasoline and becomes impregnated there- With.

The air passing to the compartment d can regulated or completely stopped by a f valve g in the tube all and from the chamber d passes along a tube` f into the tube n where 29 it mixes. with air agitated by means of the disc w which gives an energetic stirring.

2. Apparatus for automatically producing a gas of unvarying composition, comprising a receptacle for liquid fuel provided with a reservoir having fuel, a carburetor arranged to float in the fuel and having a porous wall and an air dome, means to supply air to the air dome, means to regulate the supply of air, a water tank in which the receptacle is arranged, a bell which encloses the receptacle and into which the latter discharges the gaseous mixture and which bell serves to cool said mixture and a service pipe leading from the interior of said bell. Y

3. Apparatus as claimed in claim 2, in-` cluding means to cause commingling of gaseous mixtures of varying richness prior to theirdischarge into the bell.

face wherever the level of the petrolmay be and the amount ofA air carburetted is constant for any given period of time when the fan is running the consistency of the mixture is also constant.`

The valve g allows for varying the richness of the gas obtained according to the use to which it is to be put.

For continuous running a refilling of the reservoir is all that is necessary.

The invention is not limited to the apparatusshown but includes all variations based 5 on the same principle and may have the fan replaced by any other compressor worked manually or mechanically. .What I claim as my invention and desire f,to proctect by Letters Patent is':- `5 C ll.
